摘要：Cerium modified and chromium-based catalysts using nano-gamma-Al2O3 as the carrier were prepared via incipient wetness impregnation method and investigated for the catalytic combustion of methane (CH4). The Cr-based catalysts promoted with 3 wt.% Ce displayed the most effective catalytic activity among all catalysts investigated. In addition, Ce significantly improved the catalytic performance of CH4 combustion by increasing the amount of reaction site [CrO4](ads) species on the surface of Cr-based catalysts. Introduction of Ce content also restrained the deactivation of catalysts at high calcination temperature. Cr-based catalysts modified with cerium seem to be a promising cheap and low-temperature catalyst for CH4 combustion. (C) 2013 Published by Elsevier B.V.
